nnrnrononmnnr non PIPE INSULATION.

& son and State of Kentucky, have invented a new and useful Improvement in Reinforcements for Pipe Insulation, of which the following is a specification.

. My invention is an improvement in reinforcements for pipe insulation, and has for its object to provide a device of the character specified, intended for use with pipes having insulating coverings, too soft to hold its form under the weight of the pipe which it covers and adapted to be connected with the pipe and to be arranged between the pipe and a support of the character shown and described in my co-pending application, Serial No. 851,222, filed July 15, 1914.

In the drawings: Figure 1 is a perspective View of one embodiment of the invention, Fig. 2 is a similar View ofanother embodiment, Fig. 3 is a transverse vertical section of a pipe provided with the improvement, and Figs. 4, 5, 6, 7 and 8 are perspective views of other embodiments of the invention.

The embodiment of the invention shown in Fig. 1 comprises a sheet 1 of metal of suitable weight and size, the said sheet being curved transversely as shown, to fit the peripheral surface of the insulation of the pipe. Thesheet is provided at each side edge and near its ends with slots 2, for a 3 are provided on the upper concave surface of the sheet, the said ribs being spaced apart and parallel as shown. The ribs are frustopyramidal in cross section arranged with their basesatthe sheet and preferably the ribs are as shown in Fig. 1 of considerable length, being almost as long as the sheet. The pipe 4 with which the improvement is designed to be. used isprovided with the covering 6 of insulating material, as for height that they will extend .through the coverings6 into contact with the periphery of the pipe. The ribs may be solid or chambered or recessed longitudinally as shown in Fig. 3, this form being preferable. The slots 2 are designed to receive'the ends of tie bands 5 which are passed around the pipe and the insulation for holding the reinforcea ments in place. .The ends of the tie bands Specification of Letters Patent.

purpose to be presently described, and ribs the ribs to the sheet. instance, asbestos, and the ribs 3 are of such.

are passed through the slots and are connected 111 any suitable manner to secure the reinforcements and insulation to the pipe.

In. the embodiment of the invention shown in Fig. 2, the sheet 7 is similar to the sheet 1, being curved transversely to fit the periphery of the insulation and the sheet is provided at its side ends with slots 8, 2 of the Fig. 1 of series of lugs corresponding to the slots construction. A plurality 9 are provided on the upper concave face of the sheet, the. said lugs being struck up from the material of the sheet in the present instance. of greatest width attheir base and of less width at their free ends, and they are formed by turning up the material between three slots perpendicular to the surface of the sheet. The lugs as shown are arranged in two series, the series corresponding in location to the location of the ribs 3. Both edges and near its The lugs are the ribs and the series of lugs are so spaced that they will engage the pipe far enough to one side of a vertical line through the center .of the pipe to prevent rolling of the pipe. The ribs 3'maybe cast onthe sheet or they may be cast separately and afterward secured to the sheet.

As shown in Fig. 4, each rib 10 is on a strip 11, the strip'being curved transversely 'to fit the upper concave face of the sheet and the strips 11 are secured to the'sheet by means of rivets or the like which pass through openings 12 at the ends of the strips. The ribs 10 do not extend to the ends of the strip but are spaced apart far enough to provide room for the opening 12. In Fig. 4, the strip 11 is of greater width than the base of the rib 10, so that there is a space between the side \faces of ,the rib and the side edges of the strip. In Fig. 5 the rib 13 has an extended lug 14 at each end each lug having openings 15, for receiving rivets or the.like to connect In this construction the base of the rib is curved transversely to fit the upper concave face of the sheet, and the ribs as well as the strips 11 are secured to the sheet in spaced relation, so that they will engage the pipe in approximately the same manner as shown in Fig. 3

are connected by a web 17 and the openings ribs to the sheet are in the web. The base of'the 21 at its outer side.

.rib 16 and the web 17 is curved to fit the sheet and the ribs are spaced apart in the same manner as the ribs 3 of Fig. 1.

In Fig. 7 the ribs 19 are connected by a web 20, and each rib has a lateral extension The extensions 21 are curved to fit against the concave face of the sheet but the base of the ribs and the web is the ribs rest upon a be inclined with respect to each other. The

ribs and web are placed on the sheet 27 in the manner shown, and the sheet is bent up at each side of the outer face of the rib as indicated at 25 to prevent lateral movement.

i The side edges of the sheet are then. bent outwardly and curved as indicated at 26 to fit the. insulation of the pipe. The upper face of each of the ribs 1, 10, 13 16, 19 and 23 is concave transversely to fit the periphcry of the insulation, and the upper free ends of the lugs 9 are also concave for the same purpose. In use, the reinforcements are arranged with the ribs extending throu h the insulation into contact with the perip eral siirface of the pipe. The ribs being 0 a height equal to the depth of the insulation,

. the concave face of the sheet will fit the outer face of the reinforcement closely. The

' tie bands are then placed and they reinforce- Y spaced apart from each other.

' the strip 11 is nothing more than the lugs 15 ment is in position to. engage the pipe support. Allof the weight of the pipe is borne by the ribs or the lugs and no part of the weight of the pipe comes on the insulation.

It is obvious that the sheet might extend entinlaly around thepipe but this is not essentia- It will be evident that each construction comprises essentially the sheet shaped to fit and adapted to engage the periphery of the covering, and having means on its upper concave face adapted to extend through the covering into-contact with the pipe for supporting the pipe, the said means being In Fig. 4

of Fig. 5, and may serve precisely the same purpose.

I claim K 1. A device of the character specified, comprising a sheet curved transversely andiprovided with slots at its side edges, and ribs on the concave face of the sheet and extending longitudinally thereof and spaced apart and parallel with respect to each other, the upper faces of the ribs being concave tofit 'the pipe and the sheet being curved to fit the insulation of .the pipe, said ribs being connected by an integral web, said web having openings for receiving securing means to connect the ribs to the sheet.

2. A device of the character specified, comprising a sheet curved transversely and provided with slots at its side edges, and ribs on the concave face of the sheet and extending longitudinally thereof and spaced apart and parallel with respect to each other, the upper faces of the ribs being concave to fit the pipe and the sheet being curved to fit the insulation of the pipe, each rib having anextension at each end, and each extension having anopening for receiving a securing means to permit the ribs to be connected to the sheet.

3. A device of the character specified, comprising a sheet curved transversely and provided with slots at itsside edges, and ribs on the concave face of the sheet and extending longitudinally thereof and spaced'apart' and parallel with respect to each other, the upper faces of the ribs being concave to fit the pipe and the sheet being curved to fit the insulation of the pipe, said ribs being sef cured to the sheet.

4:; A device of the characterspecified, comprising a sheet curved transversely and provided with slots at itsside edgesand ribs on the concave face of the sheet and extending, longitudinally thereof and spaced apart and parallel with respect to each other, the up per faces of the ribs being concave to fit the pipe and the sheet being curved to fit the insulation of the pipe.

5. A device of the character specified, adapted to be connected to a pipe having an insulating cover, for supporting the pipe to prevent crushing of the insulation and comprising a sheet curved to fit the periphcry of he covering and having ribs or ex- .tensions extending inwardly through the covering into contact with the pipe for supporting the said pipe to prevent the crushing of the covering.
